SAP R/3 is the former name of the enterprise resource planning software produced by SAP AG.

It is an enterprise-wide information system designed to coordinate all the resources, information, and activities needed to complete business processes such as order fulfillment or billing. SAP R/3 is arranged into distinct functional modules, covering the typical functions in place in an organization, including Financial s and Controlling (FICO), Human Resources (HR), Materials Management (MM), Sales & Distribution (SD) and Production Planning (PP). SAP typically focused on best practice methodologies for driving its software processes. SAP produced specialized modules (referred to as IS or Industry Specific) geared toward a particular market segment, such as utilities or retail.
